T-BERD®/MTS-2000 Modular Test Set
E4100 Module EXPERT OTDR Quick Setup
This quick card explains how to connect to a fiber under test, configure EXPERT OTDR test settings
using Quick Setup, run tests, and analyze results with a VIAVI T-BERD/MTS-2000 equipped with a 4100-
series OTDR module.
Equipment Requirements:
•T-BERD/MTS-2000 equipped with the following:
oFiber Optics Software Release V17.30 or
greater
oE4100 Series OTDR Module
•Fiber optic cleaning and inspection tools
•Launch Cable with connectors matching the
OTDR port and Fiber Under Test (a 20-meter
Fiber optic patch cable or leash is recommended)
•Optical Coupler to connect Launch Cable to Fiber
Under Test
Figure 1: Equipment Requirements
The following information is required to complete the test:
•Type of Fiber (Multimode or Single Mode)
•Type of Connectors (SC UPC, SC APC, LC UPC, etc.)
•Distance unit (feet, meters, miles, kilometers)
Fiber Inspection Guidelines:
•Use the VIAVI P5000i or FiberChek Probe
microscope to inspect both sides of every
connection being used (OTDR Port, Launch Cable,
bulkhead connectors, patch cords, etc.)
•Focus the fiber on the screen. If dirty, clean the
connector.
•If it appears clean, run inspection test.
•If it fails, clean the fiber and re-run inspection
test. Repeat until it passes.
Figure 2: Inspect Before You Connect (IBYC)
Connect the Launch Cable to the OTDR port:
1. Inspect the OTDR port on top of the test set.
2. Inspect the fiber end face of the Launch Cable.
3. Connect the Launch Cable to the OTDR port.

Connect to Fiber Under Test (FUT):
All fibers and connectors should be inspected prior to connection, as described on page 1. The OTDR
may be connected to the FUT via an optical patch panel (OPP) bulkhead or coupler as follows:
1. If the interface to the FUT is a patch cord, connect the patch cord to an optical coupler with
the same connector type.
2. Inspect the FUT connected to the coupler or OPP.
3. Inspect the fiber end face of the Launch Cable.
4. Connect the Launch Cable to the coupler or OPP.
Launch and Configure Test:
1. Press the ON/OFF button to turn on
the test set.
2. If files are to be saved, tap the FILE Button
and tap the results folder.
Otherwise, proceed to step 4.
3. Tap the Create Directory soft key
, enter a name for your new
folder, and tap the Enter key. All trace
files will be saved to this directory.

4. Press the HOME button to display the
Home Screen.
5. Tap the EXPERT OTDR icon
until it is yellow and highlighted .

6. Press the RESULTS button to
show the Results view.
7. Tap the Quick Setup soft key to
display Acquisition settings.

8. Configure the following basic settings for
the trace:
•Laser: Choose the wavelength(s) to
test.
•Acquisition:
oSelect Manual to manually to enter
Range and Pulse width settings.
oSelect Auto to automatically
configure Range, Pulse width, and
SmartAcq settings.
oSelect SmartAcq to perform an
acquisition with a short pulse width,
followed by an acquisition with a
longer pulse width. The first
acquisition allows events at the
beginning of the fiber to be
detected more precisely.
•Time: Select Realtime, Auto or the
desired time to sample the fiber.

Run Test:
1. Press the START/STOP button to
start the test. After auto-configuration,
the OTDR will perform a connection check
to ensure that the connection is Good.
2. If the connection is Bad, disconnect the
launch cable and reconnect as described
on pages 1 and 2, cleaning every end-face
that fails the inspection test. Also, inspect
and clean the fiber end faces in any patch
panels or connectors near the OTDR.
3. After the connection check, the OTDR will
perform acquisitions at each configured
wavelength.
4. Results may be displayed in two formats:
Trace or SmartLink.Tap the
Trace/SmartLink soft key to toggle
between views:

Trace view: Results for each wavelength
are shown in different colors in upper
display. Each event is listed in the lower
display. Events that violate loss or
reflectance pass/fail thresholds are shown
in RED.
•After selecting trace view, use the
following controls to change the display:
▪to toggle between results for
each wavelength.
▪to toggle between single event
and multiple event view in lower
screen.
Figure 9: Trace view
SmartLink view:
•In the upper display, view the FUT as a
series of icons representing each event
(connector, splice, bend, etc.).
Note: the icon-based view is not available
if Acquisition Mode = SmartAcq.
•In the center display, view summary
results per wavelength/pulse width for
the entire span. Acquisitions for which all
events are acceptable are marked with a
green check . Acquisitions with
events that exceed pass/fail thresholds
for loss or reflectance are marked with a
red .
•In the lower display, view each event that
exceeds thresholds.
•Tap an event icon and tap the Event View
soft key to view details for the
event.
